WEIGHING SCALE.

Application filed December 11, 1922 citizen of the United States,andaresident of Leetonia, in the county of Oolumblana; and State of-Ohio, have invented a new and Improved Weighing Scale, of; which thefollowing is a full, clear, and exact description.

This invention relatesto improvements in scales, an object of theinvention being to provide a scale which dispenses with the use ofsprings and weights, such as ordinarily employed, and -which embodiesbut few parts and yet is accurate in its indications.

A further object is to provide a scale which in some of its forms can bemanufactured and sold at an extremely low price so that it can be usedfor advertising purposes and given away, and which can be placed in anordinary envelope and transmitted through the mails with a minimum ofpostage. In other forms of construction it may be made for weighinglight and medium weight articles of all kinds, and is of such form andweight that it can easily be shipped or mailed in a flat package.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations, and arrangement ofparts, as will be more fully hereinafter described and pointed out inthe claim.

In the accompanying drawings- Figure 1 is a view in elevationillustrating my improved scale in operative position.

Figure 2 is a fragmentary edge view.

Figure 3 is an enlarged fragmentary View in section on the line 33, ofFigure 1.

My improved scale in its simplest form, comprises but two essentialparts namely, a board 1 and a cord 2. In employing the term board, Iwould have it understood that I use this term in its broadest possiblesense to include a sheet or plate of any material, but I preferablyemploy cardboard, celluloid, or the like for lightness andcheapnessalthough other materials may be employed to suit the trade.

In using the term cord, I employ this term to include any flexibledevice, and do not wish to be limited to the ordinary interpretation ofthe meaning of the word cord.

The board 1 is provided with two openings 3 and 4t, and the cord :2 isprojected e ia o 2 firstthrough one opening and then back through the,other, and is preferably formed withaknot 5 back of-the boardgl toprevent the movement of the cord through the, openingsafter, thecord-.is once positioned.

On one end of the cord? I preferably provide an eye 6 to engage over anail, tack, hook or; other supporting member 7,

which is preferably secured in a wall or other support, and preferablyspaced slightly from the wall yet sufficiently close thereto to preventhorizontal turning movement of the board 1.

On the lower end of the cord 2, I preferably provide a hook 8 so thatwhen the cord is positioned around a letter or package 9, the hook canengage the intermediate portion of the cord 2 and securely hold thepackage or letter, while it is being weighed. It is obvious, of course,that the invention is not limited to the particular manner of securingthe letter or package on the cord, but I believe a hook 8 such as shownto be a simple, cheap and eflicient device which not only permits thesecuring of the letter or the package, but also can lie flat when thecord is wound around the board for shipment through the mails.

On the face of the board 1, I provide a plu rality of scales, 10, 11, 12and 13. The indicating marks of these scales are concentric with theopening 3, as this opening constitutes the axis for the relativemovements of the cord 2 and the board 1, and the lower portion of thecord 2 acts as a pointer or indicator, registering with the scales andgiving the reading in accordance with the weight, or postage necessary.

The particular scales shown indicate ounces and the postage, forletters, merchandise and papers, although it is obvious that theinvention is not limited to the exact scales employed, as this may bevaried in many ways.

It is also to be understood that while I have shown a single cordpassing through the board 1 and constituting both the upper and lowerportions of a single member, it is obvious that independent membersmight be used, the only essential being that one of the cord members issecured or aflixed to the board at a point concentric with the scales,while the other member of the cord is aflixed or connected to the board1 at a point removed from the axis of the scales, as clearly shown inFigure 1.

The operation is as followshen the device is suspended as shown inFigure 1, the letter or package 2 is coupled to the lower end of thecord 2 and the weight of this package, or letter will cause the board 1to swing toward a horizontal position thus moving the scales 10, ll, 12,and 13 with relation to the lower portion of the cord 2 and this portionof the cord 2 constitutes a plumb hanging always in a vertical positionand registering with the scales to indicate the weight or postage, aswill be readily understood.

Various slight changes might be made in the general form and arrangementof parts describe-d without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claim.

I claim:

A device of the character described, cornprising an oblong board havinga scale thereon adjacent one end and having openings therein adjacentone longitudinal edge of the board, one of said openings beingconcentric ith the scale, a. cord projected through the openings andhaving a knot therein back of the board between the open-- ings, meanson the up per end of the cord for attaching the same to a support, andmeans on the lower end of the cord for connecting the same to an articleto be weighed.
